Euclidean distance degree defect of singular projective varieties
Laurenţiu G. Maxim, Jose Israel Rodriguez, Botong Wang
The unit Euclidean distance degree and the generic Euclidean distance degree are two well-studied invariants of projective varieties. These quantities measure the algebraic complex…
Combinatorial flats and Schubert varieties of subspace arrangements
Colin Crowley, Connor Simpson, Botong Wang
The lattice of flats of a matroid is combinatorially well-behaved and, when is realizable, admits a geometric model in the form of a "Schubert variety of hyp…
-vanishing theorem and a conjecture of Kollár
Ya Deng, Botong Wang
In 1995, Kollár conjectured that a smooth complex projective -fold with generically large fundamental group has Euler characteristic . In this paper, we p…
Deformation Openness of Big Fundamental Groups and Applications
Ya Deng, Chikako Mese, Botong Wang
In 2001, de Oliveira, Katzarkov, and Ramachandran conjectured that the property of smooth projective varieties having big fundamental groups is stable under small deformations. Thi…
